I'm sorry, I didn't keep any information other than for Julian Acevedo then gave his family the research a few months ago.Cornelio did not show up as part of Julian's immediate family.Below are a few things I found today that you might already have. There is more information about Cornelio, Claudio and Francisco Acevedo at Ancestry.com but I didn't renew my membership for now.Perhaps you can use the library subscription if you don't have one.
